A flying aid device for a fly-by-wire aircraft which has at least two mechanically independent control columns (M1, M2). The device (1) includes: a system (SO) for detecting multiple control corresponding to simultaneous operation of at least two of the control columns (M1, M2); and informing systems (S1, S2, S3, S4), each of which is associated with one of the control columns (M1, M2) and is intended to generate within the control column (M1, M2), when the detection system (SO) detects multiple control, a tactile sensation that informs a pilot of the aircraft who is operating the control column (M1, M2) of the multiple control.

Flying aid device for a fly-by-wire aircraft

The present invention relates to a process for the automatic control of the control surfaces of an aircraft for the low speed compensation of a lateral path deviation, in which beyond a given deflection threshold (20) of the deflected rudder (17), there is a control of a deflection, proportional to the exceeding of the threshold, of the wing surfaces (13, 14) of one of the two wings (18), said wing being that on the side of the deflected rudder (17), so as to provide a drag supplement to said wing and therefore yaw on the aircraft. Application to the take-off of large civil transport aircraft.
